'at the top is illustrated a portion of a strip on which this has occurred, and it will be readily seen that it is impossible to follow with certainty the paths-of the separate curves. For this reason it has already been proposed to render the diagrams or curves more easily distinguishable by the use of different colors. The methods hitherto devised have, however, been very complicated particularly Where more than two colors have been employed; the reason being that the color-bearing bodies are on the same side of the recording strip as the marking, point. Hence they have required to be inserted between the latter and the paper7 and consequently have occupied, when more than two in number, a considerable amount ot' space, thus causing some difficulty in changing the paper.

According to' the present invention, the magnitudes of various circuits may be recorded on the same strip by means of a sirnple measuring' instrument, in such a manner as to be clear and easily readable. The color bearing bodies are arran ed on the side of the paper remote from-t ie marking point and autonnitically change positions in definite order. Electric apparatus for other purposes in which the recording is similarly eiiected on the reverse side of the paper to the marking point, are well-known. The attempt has moreover already been made in instruments of this kind, to render the records or diagrams distinguishable either by making them inherently different, or by changing' the type. (of. U, S. l". 965,754). But by these means, the object or' this invention. namely the production of a considerable number of easily distinguishable curves, cannot be fully attained, not only because they are constructed for a single color only, but because they are inca@ pablo oi registering eurves which intersect -each other according to variations in the magnitudes.

.ufcording to t. is invention, a practical instrument for the production of several 1s automatically accompanied by 8. forward motion ot' the series of Color-bearing bodies, and a fresh color is brought beneath the marking point.

it. simple mode of execution of the idea of the invention 'is shown. tn Figs. 2 and 3 is iiinstrated the application o my invention to a, recorder for 6 circuits Comprising a single measuring instrument in which the path o' delection lor the marker is curved. The severai color-bearing" bodies fle-f, which preferably assumes the form of 'ribbons or pads, are mounted on a4 hexagonal barrel which pivots around the (i, and lie Within metal shields fthe latter are provided with curved slots or openings corresponding to the path of detieetion of 4the marker, throug'li which the recording strip r is pressed, by means of the marking point s, against the color-bearing body and is thus marked. Y

An alternative method of (ionstrurtiiitf the color changing* device :For measuring instruments in'whieh the path ot' deleetion of the, marker is eux-ved. is illustrated in Figs. 4 and ln this ease. the eolor-bear ingv bodies f-f are carried by an endless ribbon c. which traverses the rollers la; a' and passes between the support lm and the metal shield rThe recording strip runs over this shield 7), and is marked in the, manner above. described. instead ot' separate color bearing bodies. the. ribbon itseliE 'mai/f, where desired. be impregnated with the required colors. it the marker be de fleeted in a straight line. it is advisable to imite the `eolor-lwarin;Y bodies i-n they torni oi a roller, as shown in Figs. o and T: the proteetingg shield for preventingr the strip coming into direet rontart with a oloibearing body. assuming the i'orm ol' a tube with straight slots or openings.

ln Fig. is illustrated in seetiou a rolor roller within whieh rotatable eolowbearing bodies are arrangwl instead ol' rigidly mounted pads. rthe advantage of this ronstruetion is that as these rollers are rotated. a fresh portion of their surfaee is presented to the marker and their nnsable surfaee is thus considerably increased. The, device may, in fact. be so consti-urteil that tbe small rollers are automati 'ally rotated by the movement oi the main roller. so that unA usued portions ot' color suri'are areI4 rontinually being presented.

in Fig. il is illustrated a modified construetion of the multi-color roller adapted for use where the marker 2 assumes the forni ot' a knife edge whereby the. actual mark in;T is effected. The individual color-bearingl body is in this instance presented as a tine edge, which ean be provided by einploying a ribbon held between segments ot the metai roller, the outer edge of the ribbon extending slightly above the surface,

ot' the latter. The inner edge may in addi- `rover. boing to its absorbing tendem'y. is

'lo obtain Se i ,einem tion be in communication with a Color pad carrying" a eonsiderable quantity of liquid color from. which the ribbon continually reimpregnated. The aetual roloriinf dbody exposed the reeording strip is thus presented in the forni ot' a line. far more'eolor reserve than a The superiority of this iii-rire over hitherto proposed in whirb the mariti aiso eiteeted by means ot a lmin `A v coloring body in the form ot a iiue whirb rapidly exhausted oil rolor. wili be 'readily iereeived. lFurther:nore. it not praetb cable for technical reas-ons to employ suoli a color roller emboilring a eoior reservoir in a `position above the rerording strip. 'ihe Jtorni of' the color roller may. where desired. be such that it corresponds to tbe enria path. of the marker. when this morena-mt takes place over a eylinder parallel to the, anis of the ineasurin instrument.

The` new method of rerordint :recordingto the invention eonsists essentially in auto niatieally bringing the rolor-iwarinyj bodies in suceession beneath the' marliini derive and henee reduirs special designs on the marker fixed on the pon the yieldingr rharaeter of the eoior: hitherto used these latter rannot ployed in connection with the pre, tion.

big. l() illi'lsti'ates an improved colo-rings pad wherein is a rover of an absorbent material. l a porous inlet and (f a solid support ol` any suitable material. Jfor eg'iainpie, metal. ilenee onl the thin cover is posed to 1bn pressure oi the marker and 'the onlinuonsli re-iinpregnated. 'it wiil be rlearliv seen that this arrangement permit-s Y distine maras on the reverse side ol' the i iper inst yal of large blots.

'the partirular design of the eolori bod;y is important especially when the marker f/ is linileedg'ed in the known inanner. ln Fie'. l5 tbe roloi'beariir heal;v i assumes, lilo ibo pointer o' the lorin ot a, knife edge so that when the latter .is pressed down a distinct dot will be obtained at the point of rontart.

Fis'. 1i shows in detaii the Color-beaming body whieh ronsists ot the absorbent` etrver I. the porous color pad o. w-iafe'h by way of exampley may consist oi' teit. and the soiid inlet r. it `will be readily seen that the knife-edged marker d', when pressed down, is prevented from penetrating into the Color bearing body. Fig. l2 shows similar form i of the saine adapted especially for use connection with the construction illustrate in Fig. H. The coifir-bearingn body sino in Fig. 13 is distinguished by the torni ones in that the cover and the coloring body i CIJ CJi

l are made out of the same piece of fabric or ot-.l .r suitable material i ich is i:olded once or several times exceptat the point exposed to contact With the marker. The pad-like coloring body is .easiiy to be manufactured and wi" be suiiicicnt in most cases espc Where a plurality of color- Y i. bodies successively operated. ifiucfiL -a contrivance is shown in Fig. lo and is obvious that` the part of the colorbearing body l exposed to the marker l bein@ ci'niined to a very tine edge, the part ci' the absorbent cover can be .Y and reiilac the color pad. This nent offers the further advantage 'that the coloi-l'icaring bodies when exhaustcan easily be renewed. Fig. i@ illustrates :y 'Further modilication of the color-bearing body wherein a partiellar ink pad (L is used. As compared with above described this construction is disinguished by the ink pad being arranged outside the coloring body instead of Within. 'This arrangeme t. has the saine technical eli'ect that disclosed in Fig. l5 but offers besides the advantage of permitting the ink pad a to be easilyY clamped between the cheeks y?, y): `with iixed distance .71.

Fig. 'i7 shows an aiternative form which the invention may assume and the importance ot which vwill be readilyv understood when looking at Figs. 18 and 19. To obtain a plurality of coloring bodies it has bein proposed already to use a series of silk thraids. t will understood,V how ever. that the capacitv for the coloring liquid of thtl simple sillcthread is confined to a very small amount. AccordingT to my invention the thread b isextended above the ink pad o in such manner that practicallr it harms a cover for the latter. The ink pad a., which consists preterabh7 of a wool-en thread or wick, is embedded in ,Grooves provided in the solid cylinder c in such a manner that the remaining edges torni an abutment between 71 and a Jfor the marker f?. The manner in which the coloring body is automatically brought into position is ecdingly important for the reliable iforkiag oi" the new multicolor remurder.

in Fig. illustrated the relative disposition oi the marker z. pre .r frame (Z, the colo ing bodv and the switch N t0 the ctmtart pieces l--v--G oi `which the circuits to be i'ccmdcd are coiniected. By means of 'the clockwork' c or an ii'ii;ei'iiiii'1tentl v acting t'ertrwiuagnct which moves the recording strip` the point ol the marker 2 is thrust bj: ineens ol 'lu iii'fftsfir traine of against the flic ratchet hook l.y catches in saeci...ve pins s upon each movement,A

auf; lis return motion causes the prism or rol the separate color bodies to l) 1- a i oi one color, the brush of `the switch 'u being thereby advanced to the v of the. switch presents material advantages over and is quite different from that em- 80 ployed in the known single color instruments, in which the switch is either directly connected to the clockwork, or is constructed independently of the recording apparatus, although electro-magnetically operated bv the latter. There desired, the movement of the color roller may, again, be such as to only bring the colors successively beneath the marker. the roller being turned back under thc'inluence of a spring or the like Se after the last color has been used into its rst position.

Now what I claim is 1. In recording apparatus, means to produce. by means of a` single marking device imp'inging upon a common strip arranged between the` said marking device and the color bearing body, records or diagrams relating to several electric currents, and wherein a number of differently colored 10o pads or the like are in succession automat-icallv brought beneath the marking device.
